speed of goku is reduced to hulks speed so your comment does not make sense saying it and it is also HAND TO HAND so claping is not allowed if goku had normal speed it would be 2.3 times light speed fast enough to dodge sound
also the lifting power of the hulk is not important so keeping the continent together does nog matter either
you use differenct muscles to lift and punch
if you lift things you use muscles who you prepare for it if you use them to punch you use different muscles.
if you lift things you only train those muscles not the muscles to punch
goku does not train his power to lift but to punch so he is stronger then the power he can weight
hulk i have only heard that he lifts are hold together heavy things that does not prove the power of his punches
not saying he is weak but lesser powerfull in hand to hand then at lifthing/ throwing stuff
